I'm currently dealing with an engineering firm in Florida that I believe
is having the same issue.  Getting calls at 2am, 3am MDT and at the
exact same time 12 hours later to one of my numbers which has call
screening.

Left a message with their IT department, so hoping they follow up and
return my call.
